Dynamic File Reference in VBA not working

[Utterly Bamboozled]

Hi all,

Can't work out why the file reference below (myFile = "C:\Users\WP\Documents\" & Range("A1").Value & ".txt") results in Excel constantly freezing.

The file exists and the myFile string is correct...

Any ideas?

Function BarStringInfo() As String
Dim myFile As String
Dim text As String
Dim textline As String
Dim posLat As Integer
Dim posLong As Integer


[B]myFile = "C:\Users\WP\Documents\" & Range("A1").Value & ".txt"[/B]
Open myFile For Input As #1


Do Until EOF(1)
    Line Input #1, textline
    text = text & textline
Loop
Close #1
BarStringInfo = text
End Function

Thanks!

Hi,The code is working fine. please check the file names or check the code from where you are calling this function.

Thanks Arafat,

I restarted the project in a new workbook to try to isolate the issue. Unfortunately it seems through adding additional complexity to the workbook it becomes volatile. Could be the combination of user-defined functions I guess... For reference I'm also using the below function to split a long string into its component parts:

Public Function SplitString(ByVal Text1 As String, WordPos As Long) As String
    ' EXCEL VBA SplitString FUNCTION
   
    Dim CommaPos As Long
    Dim LeftBorder, RightBorder As Long
    Dim WordCounter As Long
    Dim tempstring As String
    Dim TestString As String
    Dim pos As Long
    
    pos = WordPos
    CommaPos = 0
    WordCounter = pos
    
    'LeftBorder
    If InStr(1, Text1, ",") <> 0 Then
        While WordCounter - 1 <> 0
            CommaPos = InStr(CommaPos + 1, Text1, ",")
            pos = pos - 1
            WordCounter = WordCounter - 1
        Wend
        LeftBorder = CommaPos + 1
        If InStr(LeftBorder + 1, Text1, ",") <> 0 Then
            RightBorder = InStr(LeftBorder + 1, Text1, ",")
        Else
            RightBorder = 9999
        End If
        
    Else
        LeftBorder = 1
        RightBorder = 9999
    End If
    
    SplitString = Mid(Text1, LeftBorder, (RightBorder - LeftBorder))
  
End Function

Using these two functions seems to be fine, but then when I add some Excel-defined functions the workbook becomes unstable. The Excel-functions in question are LEN() and SUBSTITUTE(). Specifically:

=SUM(LEN($A$3)-LEN(SUBSTITUTE($A$3,$F$7,"")))/LEN($F$7)

Any suggestions would be great.
Thanks
